Rstudio versão 1.2.1335 trava constantemente

Estou usando a versão mais nova (04/2019 do Rstudio no Ubuntu 18.04 (64 bits), tenho dois PC, um desktop e um laptop, o laptop nunca teve esse problema, porém o desktop trava constantemente sem nenhum sinal, pode acontecer quando não estou fazendo nada, ou seleciono algo, ou carrego um pacote, etc.

Então, o que poderia dar errado?

PS: algo com certeza trava: clique com o botão direito no terminal e selecione "inspecionar elemento". Alguns logs quando ele trava no terminal:
